Answer:
- f(x) = 5x + 10 and g(x) = 0.2x -2
- f(x) = 1/4x -1 and g(x) = 4x + 4
Step-by-step explanation:
f and g will be inverses if f(g(x)) = x.
A — f(g(x)) = 5(0.2x -2) +10 = x -10 +10 = x . . . . . inverses
B — f(g(x)) = (±√x+3)^2 +3 = x ±6√x +9 +3 ≠ x . . . . . not inverses
(even if it is g(x) = ±√(x+3), the functions are still not inverses)
C — 1/2(2x -7) +7 = x -7/2 +7 = x +7/2 ≠ x . . . . . not inverses
D — 1/4(4x +4) -1 = x +1 -1 = x . . . . . inverses
65 x 5 = 325
it’ll travel 325 miles.

Answer:
Step-by-step explanation:
The parent function denotes the simplest function (free from any horizontal/vertical stretch/compression) that represents a family of functions. In this case the term 1/4 indicates a horizontal stretch and should be removed to find the parent function of . From here we're in simplest form, since or others represent a completely different family of functions and cannot be obtained from horizontal/vertical stretches/compressions.
Jane owed her friend Dan 5 dollars. She also owed her sister Jessie 15 dollars. How much debt is Jane in? (ANSWER: -5 + -15= -20$ in debt)
Area of the whole figure = 0.5m^2 ( half * base * heighT)
Area if the circle = pi r^2 = pi k^2
So area of shaded part = 0.5m^2 - k^2 pi
